If the owner fails to sign and return the agreement granting the department the necessary rights for the installation of the screen or device within 60 days after its service on him, the department may install the screen as though the agreement had been signed unless a decision of the Department of Water Resources is requested. In the event the department and the owner of the conduit cannot agree upon the type, size, mesh, or location of the screen or device, the amount of water required for a bypass, or the time within which the screen or device shall be installed, the matter shall be submitted for determination to the Department of Water Resources, whose decision thereon shall be final and conclusive. The Department of Water Resources shall render its decision within 60 days after either the department or the owner has submitted the matter in writing and requested a decision.
